I got some Ultimate Ears headphones a while back. They sound wonderful. However, they have a little problem which has been causing me grief recently. They use an "in ear" design, with a tight fitting plug which goes inside your ear so that all the sound comes your way. Nothing wrong with that, until the plug bit starts to come off and stay in your ear when you try to remove the phones. I think this is caused by the rubber stretching slightly and becoming slack on the fitting. Whatever causes it, I don't like it as it then leaves me picking bits out of my ear canal, which doesn't look very cool.
Anyhoo, I've fixed the problem by the use of some drinking straws from McDonalds. I've put them around the outside of the rubber sleeve that goes over the headphone bit. This stops the sleeve from stretching quite so far, and makes it fit really tightly. I don't think it is the kind of thing you can get the Nobel prize for, but it works for me.

Oh, and while we are in a McDonalds mood, don't the drink lids look a lot like faces?
Scary face or coffee cup cover? You decide.
